Building waste-to-liquid fuels (WTL) plants has been historically challenging and with the nature of waste varying daily and seasonally, it has been difficult to turn waste-to-liquid fuels into a successful clean industry. But things have been looking up: two plants, one in Nevada owned by Fulcrum Bioenergy, and Enerkem’s Alberta Biofuel plant will soon both have the capacity to produce 10 million gallons of waste-to-liquid biodiesel per year. Shift Energy is trying a new approach in Brazil by focusing on the environment and job creation. Its first plant will produce about 30 million gallons of renewable fuel.
